It also turns up in employee and corporate giving to non-profits, our entire Community Investment Initiative, and everyday living in such a way to make our neighborhoods a better place. Ultimately, building community is also about the family of Parkhill, and the way we come together to have fun or to comfort each other when we’re hurting.
